Watch a Huge Freeway Overpass Get Replaced in 43 Hours

However exciting you thought a one-minute video of a freeway overpass being replaced could be, this video is at least twice as exciting as that. The Sanyuan Bridge in Beijing was recently replaced in just 43 hours, with workers dismantling the old bridge and then immediately wheeling in a premade new bridge, a process they are calling an "integrated replacement method." Using traditional construction methods, it would have taken months. As is, it is really something to behold.
